[0021] Please refer to Figure 1-2As shown in the figure, a purlin installation structure includes a steel pipe 1. There are two steel pipes 1 symmetrically arranged. Columns 2 are fixedly installed on the outer walls of the top sides of both ends of the steel pipe 1. An installation seat 3 is fixedly connected to one side of the column 2. A rotating shaft 4 is installed inside the installation seat 3. A sleeve rod 5 is movably installed on the outer wall of the rotating shaft 4. A movable rod 6 is slidably installed inside the sleeve rod 5. A locking screw 7 is rotatably installed inside the sleeve rod 5. One end of the locking screw 7 is tightly abutted against one side of the movable rod 6. A connecting plate 8 is fixedly connected to the top side of one end of the movable rod 6. A main purlin 9 is installed between the top sides of the columns 2. Five groups of two limiting holes 10 are equally spaced at both ends of the main purlin 9. A limiting bolt 11 is movably limited inside one group of the limiting holes 10. One ends of the limiting bolts 11 respectively penetrate through both ends of the connecting plate 8; during work, in practical applications, when installing the purlin, since the purlin is an important supporting part of the roof structure and there is no reinforcement for the purlin, it cannot bear the designed load, and it is easy to deform and break during use, affecting the service life of the roof. After installing the main purlin 9 on the columns 2, according to the bearing capacity required by the roof, the greater the bearing capacity, the shorter the extending length of the movable rod 6. By cooperating with the locking screw 7 to adjust the position of the movable rod 6 inside the sleeve rod 5, after adjusting to a suitable position, tighten the locking screw 7 to fix the movable rod 6. At this time, the connecting plate 8 is directly below the appropriate limiting hole 10. Install the limiting bolt 11 movably inside this group of limiting holes 10, and make one ends of the limiting bolts 11 respectively penetrate through both ends of the connecting plate 8, and limit the limiting bolt 11 through a nut sleeve, thereby connecting the movable rod 6 and the sleeve rod 5 with the main purlin 9 together, realizing the reinforcement of the purlin during installation, thereby being able to improve its bearing capacity and extend the service life of the purlin.

[0022] Please refer to Figure 3 As shown in the figure, two groups of two installation holes 12 are equally spaced at both ends of the main purlin 9;

[0023] One end of the top side of the column 2 is fixedly installed with a fixing plate 13. Two groups of two positioning holes 14 are equally spaced inside the fixing plate 13;

[0024] The other end of the column 2 is fixedly installed with a support plate 15. Four through holes are equally spaced inside the support plate 15. A nut 16 is welded at the outer edge of one side of the support plate 15. The fixing plate 13 and the support plate 15 are connected by cooperating with a fixing bolt 17;

[0025] The radii of the positioning holes 14, the mounting holes 12, and the fixing bolts 17 are all equal; during operation, purlins are basic components connected and installed on the metal roof and the structural columns and beams of the exterior wall. When installed, the purlins are horizontally distributed along the length direction of the metal roof, usually located on the main rafters, and play a role in supporting the secondary roof rafters. They are one of the main components of the building structure and are also commonly used components in steel structure buildings. Place the main purlin 9 to be installed on the top side of the column 2 between the fixing plate 13 and the support plate 15, and align the apertures of the positioning holes 14, the mounting holes 12, and the nut 16 on one side of the through hole. Connect the fixing plate 13 and the support plate 15 together through the fixing bolt 17. The fixing bolt 17 passes through the positioning hole 14, the mounting hole 12, and the nut 16 in sequence to realize the fixed installation of the main purlin 9. Through the above steps, each end of the main purlin 9 can be fixed in sequence, which can facilitate the fixing of the main purlin 9 to other structures, thereby improving the installation efficiency and accuracy, and at the same time facilitating the installation and disassembly of the purlins.

[0026] Please refer to Figure 1 , 4 As shown, five groups of two connecting pieces 18 are evenly installed on one side of the main purlin 9 at equal intervals, and two mounting through holes 19 are symmetrically opened inside each of the connecting pieces 18; during operation, through the connecting pieces 18 and the mounting through holes 19, the main purlin 9 can be connected to other secondary purlins, which is convenient for connecting other purlins, can increase the strength of the roof structure, improve its bending resistance and shear resistance, and make the entire roof more solid and stable.

[0027] Working principle: Place the main purlin 9 to be installed on the top side of the column 2 between the fixing plate 13 and the support plate 15, and align the apertures of the positioning holes 14, the mounting holes 12, and the nut 16 on one side of the through hole. Connect the fixing plate 13 and the support plate 15 together through the fixing bolt 17. The fixing bolt 17 passes through the positioning hole 14, the mounting hole 12, and the nut 16 in sequence to realize the fixed installation of the main purlin 9. Through the above steps, each end of the main purlin 9 can be fixed in sequence, which can facilitate the fixing of the main purlin 9 to other structures, thereby improving the installation efficiency and accuracy, and at the same time facilitating the installation and disassembly of the purlins;

[0028] Through the connecting pieces 18 and the mounting through holes 19, the main purlin 9 can be connected to other secondary purlins, which is convenient for connecting other purlins, can increase the strength of the roof structure, improve its bending resistance and shear resistance, and make the entire roof more solid and stable;

[0029] After installing the main purlin 9 on the column 2, according to the bearing capacity required by the roof, the greater the bearing capacity, the shorter the extension of the movable rod 6. By cooperating with the locking screw 7 to adjust the position of the movable rod 6 inside the sleeve rod 5, after adjusting to the appropriate position, tighten the locking screw 7 to fix the movable rod 6. At this time, the connecting plate 8 is directly below the appropriate limiting hole 10. The limiting bolt 11 is movably installed inside this group of limiting holes 10, and one end of the limiting bolt 11 respectively penetrates through both ends of the connecting plate 8, and the limiting bolt 11 is limited by a nut sleeve, thereby connecting the movable rod 6 and the sleeve rod 5 to the main purlin 9 together, realizing the reinforcement of the purlin during installation, thus being able to improve its bearing capacity and extend the service life of the purlin.
